Description

Technical Field

[0001] This application relates to the technical field of cement recycling, and specifically relates to a cement dust collection and reflux device. Background Art

[0002] During the production and transportation of cement, since powdery materials such as cement are prone to generate a large amount of dust, causing dust pollution, it is necessary to recycle the dust, and the cement refluxed through the recycling device can be reused.

[0003] The dust collection and reflux of cement are generally carried out through a gravity dust collector. When the gravity dust collector recycles cement, the cement is easily attached to the filter mesh, resulting in the blockage of the mesh holes of the filter mesh, affecting the recycling of cement by the gravity dust collector. Moreover, when the discharge pipe at the bottom of the gravity dust collector does not discharge cement, the cement is prone to leakage, affecting the use of the gravity dust collector.

[0004] Therefore, there is an urgent need for a cement dust collection and reflux device to solve the problem that the filter mesh is easily blocked by cement. Utility Model Content

[0005] In view of the deficiencies of the prior art, this application provides a cement dust collection and reflux device, which has the advantage of facilitating the recycling of cement and solves the problem that the filter mesh is easily blocked by cement.

[0006] To achieve the above object, this application provides the following technical solution: A cement dust collection and reflux device includes a gravity dust collector, an intake pipe and a discharge pipe that are fixedly installed on one side and the bottom of the gravity dust collector by screws. A filtering mechanism is arranged inside the gravity dust collector, and a recycling mechanism is arranged at the bottom of the gravity dust collector;

[0007] The filtering mechanism includes a driving motor 1, a support frame, a filter screen and an air outlet pipe. The driving motor 1 is arranged on one side of the gravity dust collector. One end of the rod body of the support frame is fixedly connected to the output end of the driving motor 1, and the other end of the support frame is rotatably connected to the air outlet pipe. The filter screen is arranged outside the support frame, and the air outlet pipe is fixedly connected to the other side of the gravity dust collector by screws.

[0008] When the support frame drives the filter screen to rotate, the cement attached to the outer surface of the filter screen will be thrown out, so that the cement dust will not continuously adhere to the outer surface of the filter screen, blocking the mesh holes of the filter screen, and enabling the filter screen to better filter the cement in the air.

[0009] Preferably, the air outlet pipe is communicated with the support frame through a circular hole opened on the other side of the support frame.

[0010] Preferably, the three groups of support frames and filter screens are linearly distributed inside the gravity dust collector.

[0011] Preferably, a baffle is welded at the middle position of the inner top wall of the gravity dust collector, and the baffle is located above the support frame.

[0012] Preferably, the recycling mechanism includes a second drive motor, a connecting rod, and a separation plate. The second drive motor is arranged on one side of the discharge pipe. One end of the connecting rod is fixedly connected to the output end of the second drive motor, and the other end of the connecting rod is rotatably connected to the inner side of the discharge pipe. The separation plate is fixedly connected to the outer surface of the connecting rod by screws.

[0013] Preferably, the outer side of the plate body of the separation plate is an arc surface, and the arc surface on the outer side of the separation plate is in close fit with the inner side of the discharge pipe.

[0014] In summary, the present application includes at least one of the following beneficial effects:

[0015] 1. In this cement dust collection and reflux device, when the air with cement dust is introduced into the gravity dust collector through the intake pipe, the baffle blocks the air with cement dust, causing the cement dust in the air to fall downward under the action of gravity and be collected at the bottom of the gravity dust collector. The filtered air passes through the filter screen and is discharged through the outlet pipe. At the same time, when the support frame drives the filter screen to rotate, the cement attached to the outer surface of the filter screen will be thrown out, preventing the cement dust from continuously adhering to the outer surface of the filter screen and blocking the mesh holes of the filter screen, so that the filter screen can better filter the cement in the air.

[0016] 2. In this cement dust collection and reflux device, when the cement accumulates at the bottom of the gravity dust collector, the separation plate can block the passage of the discharge pipe when it does not rotate, preventing the cement from leaking. When the separation plate rotates, it can drive the cement to be evenly discharged downward, and the cement flows back to the transportation equipment through the pipe connected to the discharge pipe, so that the cement can be recycled and reused, reducing the environmental pollution caused by the cement.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1-4 , a cement dust collection and reflux device, including a gravity dust collector 1, an air inlet pipe 2 and a discharge pipe 3 fixedly installed on one side and the bottom of the gravity dust collector 1 by screws. The air inlet pipe 2 is connected to an external pipe, and the air driving the cement enters the gravity dust collector 1 through the air inlet pipe 2 for filtration. The filtered cement is discharged through the discharge pipe 3, and the cement flows back into the transportation equipment, so that the cement can be recycled. A filtering mechanism is arranged inside the gravity dust collector 1, and a recovery mechanism is arranged at the bottom of the gravity dust collector 1.

[0024] Specifically, the filtering mechanism includes a driving motor 112, a support frame 113, a filtering screen 114 and an air outlet pipe 115. The driving motor 112 is arranged on one side of the gravity dust collector 1. One end of the rod of the support frame 113 is fixedly connected to the output end of the driving motor 112. The other end of the support frame 113 is rotatably connected to the air outlet pipe 115. The filtering screen 114 is arranged outside the support frame 113. Three groups of support frames 113 and the filtering screen 114 are linearly distributed inside the gravity dust collector 1. A baffle 111 is welded at the middle position of the inner top wall of the gravity dust collector 1. The baffle 111 is located above the support frame 113. The air outlet pipe 115 is fixedly connected to the other side of the gravity dust collector 1 by screws. The air outlet pipe 115 communicates with the support frame 113 through a circular hole opened on the other side of the support frame 113.

[0025] Through the above technical solution, when the air with cement dust enters the gravity dust collector 1 through the air inlet pipe 2, the baffle 111 blocks the air with cement dust, so that the cement dust in the air falls downward under the action of gravity and is collected at the bottom of the gravity dust collector 1. The filtered air passes through the filtering screen 114 and is discharged through the air outlet pipe 115. At the same time, the driving motor 112 is started. When the driving motor 112 drives the support frame 113 to rotate and the support frame 113 drives the filtering screen 114 to rotate, the cement attached to the outer surface of the filtering screen 114 will be thrown out, so that the cement dust will not continuously adhere to the outer surface of the filtering screen 114 and block the mesh holes of the filtering screen 114, enabling the filtering screen 114 to better filter the cement in the air and facilitating the gravity dust collector 1 to recover the cement.

[0026] Specifically, the recycling mechanism includes a second driving motor 211, a connecting rod 212, and a separating plate 213. The second driving motor 211 is disposed on one side of the discharge pipe 3. One end of the connecting rod 212 is fixedly connected to the output end of the second driving motor 211, and the other end of the connecting rod 212 is rotatably connected to the inner side of the discharge pipe 3. The separating plate 213 is fixedly connected to the outer surface of the connecting rod 212 by screws. The outer side of the plate body of the separating plate 213 is an arc surface, and the arc surface on the outer side of the separating plate 213 is in close fit with the inner side of the discharge pipe 3.

[0027] Through the above technical solution, when cement accumulates at the bottom of the gravity dust collector 1, the channel of the discharge pipe 3 can be closed when the separating plate 213 does not rotate, so that the cement will not leak. Start the second driving motor 211, and the second driving motor 211 drives the connecting rod 212 to rotate. When the separating plate 213 rotates, it can drive the cement to be evenly discharged downward. The cement flows back to the transportation equipment through the pipe connected to the discharge pipe 3, so that the cement can be recycled and reused, reducing the environmental pollution caused by the cement.

[0028] During use, when the support frame 113 drives the filter screen 114 to rotate, the cement attached to the outer surface of the filter screen 114 will be thrown out, so that the cement dust will not continuously adhere to the outer surface of the filter screen 114 and block the mesh holes of the filter screen 114, enabling the filter screen 114 to better filter the cement in the air.

[0029] Although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
